Specification of Letters Patent.

Patented Nov. 3, 1908.

Application fled Kay 89, 1808. Serial No. 585,816.

To all whom it may concern:

Be it known that we, HARRY K. Famsu. and Howsnn L. FAIRALL, citizens ofthe United States, residing at Hi hland, in the county of SanBernardino, tate of California, have invented certain new and useful In])rovements in Hinges; and we do hereby dec are the followin to be afull, clear, and exact description 0 the invention, such as will enableothers skilled in the art to which it a pertains to make and use thesame.

T 1e invention relates to a hinge and more articnlarly to the class ofhinges adapted for doors, gates or the like whereby the latter u onopening thereof may be automaticallv roug t to a closed position.

he primary object of the invention is the provision of a hinge or hingeseach comprismg a strip of material bent on itself to form a spiralintermediate portion terminating in securing ears and which spiralintermediate portion is traversed b a slotted member or arm forming theor portion or half of the hinge so that when the door or glate is swungto an open position the same w] rise by the movement of the said otherhinge section upon the spiral and upon the release of the door the samewill be antomatically shut. With this and other objects in view theinvention consists in the construction, combination and arrangement ofparts as will be hereinafter more fully described and as will beillustrated in the accompanying drawings which disclose the preferredembodiment of the invention, however changes, variations andmodifications may be made as come properly within the scope of theclaims hereunto appended without departing from the spirit of theinvention.

In the drawin s:--Figure 1 is an elevation of a door wit the hingessecured thereto. 2 is a plan view of a. door in an open position withthe invention ap lied t ereto. Fig. 3 is a perspective view 0 one hingesection which latter is adapted to be carried by the door.

Similar reference characters indicate correspondin parts throughout theseveral views in t e draw' 1n the drawings, 1: e numeral 5 des' ates thedoor proper and 6 the side of the ame oi said door. Near the upper andlower end extremities of the door near one side edge thereof are members7 each forming one section of a h' and includes outwardly divergingextensions 8 terminating in an arm 9 having opposed flattened faces 10and extending at a slight angle outwardly with respect to the sions 8,and w ich arm has an elongated straight slot 11 enga iug a. spiral 12formed of a twisted strip 0 material 13 which latter is bent on itselfat opposite terminals of the spiral to form otl'sets or right angularlydisposed extensions 1d which latter terminate in securing extremities 15each of which are arran d in the same plane and are secured by asteners16 to the frame 6 of the door. This strip of material forms the otherhinge section and is adapted to automatically close the door 5 when inan open position.

In each of the extensions 8 are fasteners 17 to secure the same to thedoor 5. It is of course understood that two of these memhere 7 are usedand also two of the strips 13- for hingedly mounting a door in its frameand which are positioned near opposite extremities thereof.

It will be obvious that when the door is swung open the slotted arms 9will traverse the spiral portions 12 of the strips 13 in an upwarddirection and thereby raising the door as well as bringing the same toan open position. As soon as the door is released the we 1'. thereofwill cause the slotled arms of tie members 7 to travel downward u n thespiral rtions of the strips carried y the frame oFllIe door and therebyautomatically swinging the door to its closed osition. In thisconstruction of hinge it oes away with the necessity of springs toautomatically close a door as the spiral por tion of a hinge causes theshutting of said door.

What is claimed is 1. A hinge comprising a strip of material twisted toorm a spiral portion terminating at opposite ends in ofl'set securingextremities and a member having secnmng extensions and a slotted armengaging the spiral portion of the strip.

2.
